KAIST doctoral student wins prize at 2014 International Military Science and Technology Fair

Min-Kyu Yoo (far left), a doctoral student in the Department of Materials Science Engineering, KAIST, received a silver prize at the 2014 International Military Science and Technology Fair held from May 29 to June 1, 2014 at KINTEX, Ilsan City, Korea.

Yoo presented a paper on aluminum composite materials that were reinforced by carbon nanotubes. Carbon nanotubes reinforced aluminum composite materials have strong mechanical properties, and some nations have used them to manufacture battle tanks. 

Aluminum generates hydrogen in an alkaline solution. Utilizing this property and the galvanic corrosion of carbon nanotubes and aluminums, Yoo developed a hydrogen energy system that is fueled with composite materials of carbon nanotube reinforced aluminum. He produced 5 kW electric power and maintained it 22 days using 10 kg of the composite materials for a proton exchange membrane fuel cell and its auxiliary power system.

Yoo’s research will alleviate the difficulty of transporting fuels during wartime and can be applied to the development of an auxiliary power system for next generation aircrafts and battle tanks.
